What we offer

Procurement

Procurement

Since 1986, Telcona's ISO 9001-certified procurement service connects you with tested components from leading global manufacturers. Flexible quantities, reliable supply chains, and on-time delivery — from small batches to full-scale production.

Engineering

Engineering

Our multidisciplinary team supports you from concept to series production — covering schematic design, PCB layout, prototyping, and EMC validation. Precise engineering solutions tailored to your exact technical requirements.

Components development

Components development

When standard components fall short, we develop custom solutions from scratch. From initial specification through validation to series handover, our team builds electronic, electromechanical, and acoustic components to your exact performance and cost targets.

Crystal & Circuit Testing

Crystal & Circuit Testing

We measure the true equivalent circuit of quartz crystals and validate their behavior in your actual oscillator circuit. The result is a verified, application-specific specification that eliminates oscillation failures and supports confident second-source qualification.

Logistics
